Duna-Ipoly National Park
The Duna-Ipoly National Park, involving the wooded ranges along the Danube Bend and the relatively untouched part of the River Ipoly Valley, was established in 1997. It is situated north of Budapest. Its total area covers 60,314 hectares. The uniqueness of the region derives from the interaction between three different main landscape forms such as river valleys, mountains, and the lowland. Also it is worth visiting the castle ruins of Drégely vár in Drégelypalánk.
